Windows Firewall: Private: Display a notification
Select this option to have Windows Firewall with Advanced Security display notifications to the user when a program is blocked from receiving inbound connections.
Note When the Apply local firewall rules setting is configured to No, Microsoft recommends also configuring the Display a notification setting to No. Otherwise, users will continue to receive messages that ask if they want to unblock a restricted inbound connection, but the user's response will be ignored.
